The 3,600-passenger cruise ship will depart later that day at 3 p.m. on a 2-night preview cruise-to-nowhere with special guests, travel agents and members of the media aboard.

On its return Tuesday, it will then depart on its official maiden Eastern Caribbean cruise.

Here are some key features of the Royal Princess:

Atrium: An expanded atrium designed to enhance the lively street-café atmosphere. There are more open space for viewing live entertainment in the Piazza from decks 6 and 7, as well as new venues that appear to float mid-air. The Atrium decks have several restaurants and bars for cruisers to enjoy

Largest outdoor movie screen at sea – On Royal Princess, not only is the Movies Under the Stars screen 30 percent larger than Princess Cruises’ current screens, it will be the largest at sea.

New adults-only pool on top decks of the ship, with seven plush private cabanas that appear to be floating on the water, two additional pools

SeaWalk: a top-deck glass-bottomed enclosed walkway on the ship’s starboard side extending more than 28 feet beyond the edge of the vessel
